Handles.ArrowHandleCap

파라미터

설명

Draw an arrow like those used by the move tool.

On EventType.Layout event, calculates handle distance to mouse and calls HandleUtility.AddControl accordingly.

On EventType.Repaint event, draws the handle shape.

Note: Use HandleUtility.GetHandleSize where you might want to have constant screen-sized handles.

// Draw one circle on each axis of any GameObject
// that has the "DummyScript.cs" script attached.

// DummyScriptEditor.cs (place this in Editor folder)
[CustomEditor(typeof(DummyScript))]
public class DummyScriptEditor : Editor
{
    float size = 1;

    void OnSceneGUI()
    {
        if(Event.current.type == EventType.Repaint)
        {
            Transform transform = (target as DummyScript).transform;
            Handles.color = Color.red;
                Handles.ArrowHandleCap(0,
                    transform.position + new Vector3(5, 0, 0),
                    transform.rotation * Quaternion.LookRotation(new Vector3(1, 0, 0)),
                    size,
                EventType.Repaint);
